Here the HP Z8 G4 tower workstation comes with two Intel Xeon Gold 6234 processors (8 cores each, 3.30GHz base clock) alongside 128GB of DDR4. For storage it carries an 8TB 7.2K SATA hard drive and a 512GB NVMe SSD (8.51TB combined), occupying one bay of the 4-bay 3.5-inch chassis and leaving three free.
Supporting hardware includes integrated SATA RAID, 1GbE networking (Intel I219LM) and a 1125W power supply. Also included: Windows 11 Pro as the listed operating system.
Designers and engineers get the NVIDIA RTX A4500 Ampere for CAD and 3D viewport work, with 16 cores for simulation and rendering tasks. Capacity can grow later by filling the free bays, without a change of chassis.
That is twice the memory of a lighter Z8 G4 build, which matters most for virtual machines and caching. Its Gold-tier processors sit a step above the entry CPU options for this model.
Our Johannesburg team inspects and bench-tests the workstation and wipes any stored data before it is released as certified refurbished.
